GEORGE L. ODGERS, OF BONNE TERRE, MISSOURI, ASSIGUOR OF ONE-HALF TO P.A. BENHAM, OF SAME PLACE.

NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 510,285, dated December5, 1893..

Application filed October 9,1893. Serial No. 487.559- (No model.)

citizen of the United States, residing at Room Torre, in the county ofSt. Francois and State 5 of Missouri, have invented certain new anduseful Improvements in Nut-Locks; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same.

This invention relates to nut-looks, and it consists in certainimprovements therein which will be presently described.

Referring to the drawings: Figure 1 is a perspective view of abuttingrail sections showing the improved construction applied thereto. Fig. 2is a like view with the outer frame or plate removed and shown inadvance of the main figure. Fig. 3 isa transverse ver- 20 tical sectionof the device as shown in'Fig. 1,

taken through one of the locking bolts.

Similar letters of reference are employed to indicate correspondingparts in the several views.

Referring to the drawings, theletterA designates'two abutting railsections which are of any ordinary form of construction, having boltopenings extending transversely through the web thereof at properintervals. On both sides of the rail sections, over thejoint formed bythe abutting ends, are placed fish plates, one plate, B, being withoutbase flange, and the other plate, 0, having a base flange, c, adapted torest on the flanges of rail sections, and indicating that either formmay be employed. In each instance, however, the plates have boltopenings which align with the bolt openings in the webs of the railsections and receive locking bolts,D,on which are mounted nuts, cl. Theopposite ends of the fish plates, as well as the adjacent portions ofthe rail sections, are also provided with bolt openings through whichare passed securing bolts, for a purpose which will be presently de- 5scribed.

Over the nuts, d, blocks,;E, are fitted, said blocks each having anopening, 6, therein simulating the shape of said nuts, or said openingsmay be formed in the contour of two squares intersecting eachotherdiametri- 5o cally so as to accommodate an irregular position ofthe nuts, d. Each of the blocks has a lower angular flange, 6 whichbears against the flange, c, of the fish plate, O, or directly againstthe rail flange, according as either of the forms of fish plates isemployed. The upper part of each block is constructed with a verticalflange, e, which rests against the under side of the rail head, andforms a top shoulder or rest, a

Over the blocks, E, and resting against the flanges, 6 thereof at itslower edge, is a looking frame or plate, F, which is recessedlongitudinally at the back portion thereof by being projected in frontand inclined divergently from the top downwardly, the lower edgebeingbeveled to partake of the same plane of inclination as the flanges, 6 ofthe said blocks to institute a close fitting adjustment. The centralprojected portion of the frame or plate, F, is formed with one or moreopenings, as atf and f to fit over the nuts, cl, and provide upper andlower longitudinal bars, f and f", which are adapted to be connected bya cross-bar, f ora plurality of the same. The upper bar,f',.is formedwith one or more locking lugs, f which fit in the spaces between theblocks, E, and serve as guides in properly applying the said frame orplate and also to hold the latter in position. The opposite ends of saidframe or plate recede backwardly and are formed with bolt openings, fthrough which the projecting ends of the bolts, 0 are passed, the latterthen having split keys or linchpins, 0 or other suitable locking devicesinserted through openings there into hold the said frame plate in lockedposition.

The several parts of the device are constructed of suitable metal and byany preferred manner. They can be readily applied in looking position ordetached, and, when properly applied, a secure locking means isprovided.

It is obviously apparent that many minor changes in the proportion andconstruction of the several parts might be made and substituted forthose shown and described so long as they are within the scope of theinvention without departingfrom the nature or spirit of the latter.

Having thus described the invention, what is claimed as new is- 1. In anut lock, the combination with the rail sections, fish plates, andlocking bolts and nuts, of a series of individual blocks fitted oversaid nuts, and a rigid locking plate or frame applied over said blocks,substantially as described.

2. In a nut lock, the combination with the rail sections, fish plates,and locking bolts and nuts, of a series of blocks fitted over said nuts,a locking plate or frame applied over said blocks, and securing boltsfor said frame or, plate, substantially as described.

3. In a nut lock, the combination with the nuts, of a series of blocksfitted thereover having lower flanges, and a locking frame or plateapplied over said blocks, substantially as described.

4. In a nut lock, the combination with the nuts, of a series of blocksfitted thereover, and a locking plate applied over the blocks andhavingone or more lugs which are adapted to fit in the spaces betweensaid blocks, substantially as described.

5. In a nut lock, the combination of the nuts, of a series of blocksfitted thereover and provided with lower flanges, a locking plate orframe mounted over said blocks and provided with a central outwardprojection with one or more openings therein and forming upper and lowerbars, said upper bar having one or more lugs fitting between saidblocks, and end securing bolts for removably holding said plate or framein position, substantially as described.

I'm-testimony whereof I aflix my signature in presence of two witnesses.

GEORGE L. ODGERS.
